I noticed that the package 0.93, in the class folder there is a file called piCalD3commentContent.class, which refers to the integration of comments from forum to piCal.
There are no such files in the archive I'm distributing.
Perhaps, it is made by photositelinks.
In the setup of the forum's comment piCal i must report this: piCal::piCalD3commentContent::pical ?
I cannot assert it till I read the plugin...
This is the pattern for Duplicatable V2 modules.
If you install "piCal" with the dirname of "event", set it
If you use D3 modules, set it
